| Outline of Final Research Achievements |
We have developing scintillator materials for medical devices such as positron emission tomography (PET). Scintillators are a kind of phosophor materials, which convert high energy radiation into low energy photons. Typical requirements of scintillators for PET include high light yield and fast decay time. In this study, we used organic-inorganic layered perovskite-type compounds. Phenethylamine with substituent group was incorporated into the organic layer to enhance scintilaltion light output. Throughout this study, we fabricated the hybrid compounds, which showed 20000 photons/MeV.

| Academic Significance and Societal Importance of the Research Achievements |
高齢化に伴い、癌診断装置の需要がますます増加していくものと予想される。今回、開発したシンチレータの性能は、ポジトロン断層法で使用されているシンチレータＧＳＯ：Ｃｅよりも優れた発行特性を示すものである。今回の成果を活用し、大きな単結晶を育成する技術を開発することで、ポジトロン断層法の癌解像度がさらに向上するものと期待される。
